The Master Plan of Transportation is the network of key transportation facilities which are needed to serve existing and future development in Prince George's County. These facilities include existing and planned roadways which interconnect our neighborhoods, commercial centers, and employment centers. The last Master Plan of Transportation for the entire county was completed in 1982, and that plan has since been amended by each area Master Plan which has been approved since that time.

Existing rights-of-way along State highways should be verified at the State Highway Administration's District 3 office at 9300 Kenilworth Avenue, Greenbelt. Along county roadways, existing rights-of-way can be verified at the Department of Public Works and Transportation, Office of Project Management at 9400 Peppercorn Place, Largo. Within municipalities, the local municipal office should be contacted. Future (planned) rights-of-way can be obtained by contacting the Transportation Planning Section or by logging on to the Prince George Atlas website.

Before a new subdivision can be approved by the Planning Board, county regulations require that the Planning Board determine that transportation facilities in the vicinity of the subdivision will be adequate to serve it. The Planning Board determines adequacy on the basis of information submitted by the subdivider as well as agencies responsible for overseeing the construction of the required facilities, such as the State Highway Administration and the County Department of Public Works and Transportation.

Counts of average daily traffic (ADT) are available for State highways in a map format by contacting the SHA Map Store at 211 East Madison Street, Baltimore, MD or by visiting the State Highway Administration's website.
